HV

where v is the order of the Struve function and
is the
gamma function.

Dataplot computes this function using the STVH0, STVH1, and
STVHV routines from "Computation of Special Functions" (see
the Reference section below).

Syntax 1:

LET <y> = HV(<x>,<v>)
<SUBSET/EXCEPT/FOR qualification>
where <x> is a number, variable or parameter;
<v> is a number, parameter, or variable;
<y> is a variable or a parameter (depending on what
<x> and <v> are) where the computed Struve
function values are stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.

Dataplot supports the Struve function for non-negative real
x and for orders between -8.5 and 12.5. This syntax is used
for arbitrary order.

Syntax 2:

LET <y> = H0(<x>)
<SUBSET/EXCEPT/FOR qualification>
where <x> is a number, variable or parameter;
<y> is a variable or a parameter (depending on what <x>
is) where the computed Struve function values are
stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.

Dataplot supports the Struve function for non-negative real
x. This syntax is used for the Struve function of order 0.

Syntax 3:

LET <y> = H1(<x>)
<SUBSET/EXCEPT/FOR qualification>
where <x> is a number, variable or parameter;
<y> is a variable or a parameter (depending on what
<x> is) where the computed Struve function
values are stored;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.

Dataplot supports the Struve function for non-negative real
x. This syntax is used for the Struve function of order 1.
